Re: Generating CW-morse signals with a straight key

[Harald Fritzsche (DD0VS)]

Dear Frank, ALbin, Gorkem and all others,

thanks for prompt and prominent answers.

@Frank: i am also interested on your SW, yes, i know DttSP, there is a
link inside to some JACK stuff. I need to say that i am not familiar
with that audio system. What i am understanding from some reading is,
that FLEX1000 (means DttSP) interacts internally via JACK audio system.
Now this gives me a hint, why this decision has been made.
Would be great for me to understand how this can work for gnuradio. I am
using a RPI4 currently. It seems to be tricky to get JACK running on
this devices.
(BTW: readings about Tayloe mixers some times ago restarts my interest
in HAM Radio :-)

@Albin, Gorkem: thanks for your input, i personally think the audio
solution (modulated CW) isn't that elegant, nevertheless, its not out
of scope for me.

For CW generated from text there is one solution on cgran, see
gr-satnogs and another solution (not running for me, since it needs
GR38) is from Barry: gr-morse-code-gen (github).

The last one is click free (acc. the grc graph).

Meanwhile i have a CW keyboard input programed based on gr-analog,
gr-satnogs and gr-morse-code-gen :-) But to attach a key ...

One comment: audio latency may not disturb to much, because the idea is
to attach an automated CW (contest logging program) to this keyer port.
Only in rare cases a paddle or key is needed, in this cases latency
must be accpeted. (also not elegant, i know)
